  • How to install Zabbix Agent on Debian 11 Bullseye - Linux Shout

    If you already have a Zabbix server installed and want to monitor any target machine or server then to make things easy use its Agent. Here in this tutorial, we will learn the steps to install Zabbix Agent on Debian 11 Bullseye.

    The Zabbix agent is part of the whole open-source network monitoring tool offered by the developers of it. That is required to actively monitor a target/server or to query its resources (HDD, RAM, CPU, database, general statistics, network, etc.). The agent runs as a service on the server or desktops. It is not necessary because the Zabbix server can also collect information using, for example, SNMP, SSH, IPMI, macros, etc. After that, the admin can evaluate the data of various machines using the web interface. Based on the information provided by the Agent the server part of Zabbix can generate alerts in a case of emergency to admins via various channels (email, SMS, etc.).

  • How to Enable & Disable AppArmor on Linux Mint 20 - LinuxCapable

    Linux Mint distributions come with AppArmor, a Linux kernel security module that allows the system administrator to restrict programs’ capabilities with per-program profiles. Profiles can allow network access, raw socket access, and permission to read, write, or execute files on matching paths. Rhel family users would notice this is similar to Selinux; however, they work differently and have pros and cons.

    The following will cover how to enable and disable AppArmor and individual profiles; usually, most users would not need to adjust any settings with AppArmor, but if the need arises, some simple commands are all needed in the tutorial will explain.

  • How to Customise the GNOME Shell Clock - OMG! Ubuntu!

    GNOME Shell is an eminently customisable desktop environment — even though it’s not always apparent.

    Take the clock.

    Sitting at the top of every modern Ubuntu desktop, this titular timepiece couldn’t be any more conspicuous.

    And yet… The only clock customisation GNOME Shell supports out-of-the-box is a choice of showing a 12 hour clock or a 24 hour clock.

    For most people this is fine. It’s a sane default: it tells you the date and time.

  • How to Install MariaDB 10.7 on CentOS 8 Stream

    MariaDB is one of the most popular open-source databases next to its originator MySQL. The original creators of MySQL developed MariaDB in response to fears that MySQL would suddenly become a paid service due to Oracle acquiring it in 2010. With its history of doing similar tactics, the developers behind MariaDB have promised to keep it open source and free from such fears as what has happened to MySQL.

    MariaDB has become just as popular as MySQL with developers, with advanced clustering with Galera Cluster 4, faster cache/indexes, storage engines, and features/extensions that you won’t find in MySQL.

  • How to Install and Use Rdiff-backup in RHEL Systems

    Data backup is an important element of successful Linux administration. It is a skill set mastered by most Linux users and administrators. Whether you are after remote or local data backup solutions, it is important to consider the efficiency of a backup tool like Rdiff-backup.

    Rdiff-backup data backup utility is attributed as a cross-platform data backup solution. Therefore, its usability also extends to FreeBSD and macOS operating system platforms. This cross-platform flexibility is partially a result of the Rdiff-backup tool being written in Python.

  • How to use ss Command (Monitor Network Connections) - Unixcop the Unix / Linux the admins deams

    The ss command is a tool used to dump socket statistics and displays information in similar fashion (although simpler and faster) to netstat. The ss command can also display even more TCP and state information than most other tools. Because ss is the new netstat, we’re going to take a look at how to make use of this tool so that you can more easily gain information about your Linux machine and what’s going on with network connections.

    The ss command-line utility can display stats for the likes of PACKET, TCP, UDP, DCCP, RAW, and Unix domain sockets. The replacement for netstat is easier to use (compare the man pages to get an immediate idea of how much easier ss is).

  • How To Install MongoDB on AlmaLinux 9 - idroot

    In this tutorial, we will show you how to install MongoDB on AlmaLinux 9. For those of you who didn’t know, MongoDB is a high-performance, highly scalable document-oriented NoSQL database. Unlike in SQL databases where data is stored in rows and columns inside tables, in MongoDB, data is structured in JSON-like format inside records which are referred to as documents. The open-source attribute of MongoDB as a database software makes it an ideal candidate for almost any database-related project. This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the MongoDB NoSQL database on AlmaLinux 9. You can follow the same instructions for CentOS and Rocky Linux.

  • Self-host a Ghost Blog With Traefik

    Ghost is a very popular open-source content management system. Started as an alternative to WordPress and it went on to become an alternative to Substack by focusing on membership and newsletter. The creators of Ghost offer managed Pro hosting but it may not fit everyone's budget. Alternatively, you can self-host it on your own cloud servers. On Linux handbook, we already have a guide on deploying Ghost with Docker in a reverse proxy setup. Instead of Ngnix reverse proxy, you can also use another software called Traefik with Docker. It is a popular open-source cloud-native application proxy, API Gateway, Edge-router, and more. I use Traefik to secure my websites using an SSL certificate obtained from Let's Encrypt. Once deployed, Traefik can automatically manage your certificates and their renewals. In this tutorial, I'll share the necessary steps for deploying a Ghost blog with Docker and Traefik.
